Abstract (en)
[origin: EP0820940A2] A flexible pouch (1) having a filter (5), whereby the contents of the pouch exit the pouch through a filter. A multi-compartment flexible pouch, the compartments having a common interchange and removable sealing means (13) separating the compartment. A process for making a multi-compartment pouch having a common interchange, comprising folding as first sheet of barrier material in half along its width, folding a second sheet of barrier material in half along its width, joining a folded part of the first sheet with a folded part of the second sheet, folding successive sheets in half along the sheet width and joining the folded part of each successive sheet of barrier material with the folded part of the next sheet of barrier material, and joining a folded part of the last sheet with a folded part of the first sheet, said folding taking place to form an axis of radial symmetry around an interchange common to all the compartments.
